Hydraulic Bolt Tensioner, 48 mm Bolt, M48 x 5.0, 75 mm A/F - Enerpac PGTD4875S

This hydraulic bolt tensioner preloads M48 x 5.0 bolts purely hydraulically, applying the clamping force without torque and without friction on the thread. The double-deck design delivers even, repeatable tension even on hard to reach flanges in wind, steam and gas turbines.

Benefits

• Even preload across multiple bolts with no friction losses, for secure flange joints
• Auto-retract piston speeds up the work cycle
• Zinc coating gives the puller lasting corrosion protection
• Interchangeable bridge and long-life seals for extended service intervals
• Mechanical over-stroke preventer protects the cylinder
• Quick-disconnect coupler for a safe, fast hydraulic connection
